At present, many pesticidal compositions have been developed and used, but they are not necessarily sufficient to control pests, and therefore, the appearance of highly active pesticidal compositions is desired. In particular, when applied to soil, the emergence of a highly active pesticidal composition capable of simultaneously controlling pests in the soil and pests in the ground part is desired.

An object of the present invention is to provide a pesticidal composition which has a wide spectrum of pesticidal spectrum and is highly active and has a long-lasting effect, and a method for comprehensively controlling the pesticidal composition.

The present inventors made various studies and acquired the knowledge that a highly active pesticidal composition is obtained by combining specific compounds, and completed the present invention.

That is, the present invention provides at least one organophosphorus compound (A) (hereinafter abbreviated as compound A) selected from the group consisting of phosphthiazate and imyafoss (all common names), clothianidine, At least one compound (B) selected from the group consisting of dinotefuran, thiamethoxam, tefluthrin, silafluorene, chlorfluazuron, flufenoxuron and teflubenzuron (all common names) ( Hereinafter, the present invention relates to a pesticidal composition (except for the combination of phosphthiazate and tefluthrin) containing Compound B as an active ingredient.

The present invention also relates to a method for controlling pests by applying an effective amount of a pesticide of the composition.

The pesticidal composition of the present invention has aerobic action in pest control, has higher control activity, longer lasting effect, and immediate effect than using each agent alone, Effective for prevention and the like.

Phosthiazate and imicyafos each have optical isomers, but Compound A of the present invention includes both an optically active substance and a racemate.

In the compound B of the present invention, clothianidin, dinotefuran and thiamethoxam are neonicotinoid compounds. Tefluthrin and silafluofen are pyrethroid compounds. Chlorfluazuron, flufenoxuron and teflubenzuron are benzoylurea compounds.

The mixing ratio of the compound A and the compound B needs to be appropriately adjusted according to the form of the preparation, the method of application, the weather conditions, the type and the development situation of the pest to be controlled, and can not be determined uniformly. 1:20, preferably 1: 0.04 to 1:10. In particular, in the case where compound A is phosphthiazate and compound B is clothianidine, the mixing ratio is preferably 1: 0.01 to 1:10 by weight, more preferably 1: 0.02 to 1: 7.

The pesticidal composition of the present invention can be applied at an active ingredient concentration of, for example, 10 to 10,000 ppm, preferably 100 to 5,000 ppm. The active ingredient concentration can be appropriately adjusted according to the mixing ratio of the compound A and the compound B, the form of the preparation, the method of application, weather conditions, the type of pests to be controlled and the development situation.

The dosage of Compound A and Compound B per unit area (effective amount of pesticide) cannot be determined uniformly as described above, but for example, Compound A is 500 to 10,000 g / ha, preferably 750 to 5,000 g / ha. , Compound B is 100 to 10,000 g / ha, preferably 200 to 5,000 g / ha.
